Allium Chromosome Aberration Test for Evaluation Effect of Cleaning Municipal Water with Constructed Wetland (CW) in Sveti Tomaž, Slovenia

Abstract

® ; Allium metaphase test; Chromosome damage Abstract We show the effectiveness of the communal waste water cleaning plant of the type LIMNOWET ® Constructed Wetlands (CW). The tests were done with the Allium metaphase test and show the degree of genotoxicity, by observing the aberrations of the metaphasic chromosomes of the plant Allium cepa L. that are evoked by genotoxic substances in the polluted water. The CW plant reduced the degree of genotoxicity 29.0% to 3.5% (the Fisher's Exact test: p=9.2e-13<0,00001). Therefore CW is a very effective ecoremediation technique, since it removes up to 96% of waste.
